Abstract
Circuitry, which includes a first switching transistor element having a first gate, a second switching transistor element having a second gate, a third switching transistor element having a third gate, and a fourth switching transistor element having a fourth gate, is disclosed. The first switching transistor element and the third switching transistor element are coupled in series between a first power source and a first downstream circuit. The second switching transistor element and the fourth switching transistor element are coupled in series between a second power source and the first downstream circuit. A voltage swing at the first gate and a voltage swing at the second gate are both about equal to a first voltage magnitude. A voltage swing at the third gate and a voltage swing at the fourth gate are both about equal to a second voltage magnitude.
